Welcome @Dotty27. The cost of IVF can be horrendous and not all clinics or fertility specialists are created equal. We did 3 cycles with our first FS and that was a total waste of money, so with hindsight we'd have been better going straight to our second FS, but we didn't know about him at the time. They were both with the same clinic, so same cost per cycle. With the cheaper clinics, some just wouldn't offer the services you need, so I'd think that would be a waste for you (I think we had similar issues).
Costs seem to vary state to state, so it will depend where you are. We're in Queensland and it seems to be cheaper than Melbourne at least. Drugs are generally covered by PBS, so they should be the same cost. It will also depend if you need ICSI and possible PICSI/HA-ICSI as the extras can add up and the cost of any extras can vary between clinics, with some things being cheaper at one and vice versa.
With Medicare the first cycle per calendar year is also more expensive until you reach the safety net. So a cycle would cost us $7860 and with the full safety net we got back $5341.90, plus we had ICSI for $800 and we got back $526.10 and PICSI $200 ? I think (no refund) and Embryoscope $495 (no refund). For the first cycle in a calendar year it was about $500-800 more as we got less back from Medicare.
Good luck with your decision making.
